Not my favorite. These bottle were a pain to use. Plus not very cost effective due to buying refills for the liners all the time.

I used these for my daughter and thought they were a waste of money. you buy the drops ins because of easy clean up but the price adds up quickly. I would rather just wash the bottle, bought something different for my son

These were the first thing I tried with my little one when I have to introduce a bottle. This was my first choice because my mom used to use these. I found them difficult to use and hard to keep the air out.

I do not like the liners in bottles. I think it is a big waste of money, especially in this rough economy. To each their own though.

Great for breastfeeding mom's and excellent eliminates the fact that its hard to wash the bottom of a bottle so they are the perfect bottle bottomless and technically always clean and perfect breast milk storage. Cons are the simple fact that you ahve to constantly spend money on the liners.

I like these bottles compared to some of the other brands I prefer either these ones or dr brwns are the only 2 I have used on ym children and I have not 1 cmplaint

I had a hard time finding the perfect bottle for my baby since she was only breastfed and hated the flavor of silione, however she did like this one for a short while. The drop ins are convenient if you hate washing bottles, the air can easily be removed to prevent colic and the material is very resistant; however, spending for drop-ins (assuming you are a mom who bottle feeds only) can add up overtime to the same price as maybe buying several bottles from other prestigious brands like Advent bottles, the drop-in liners also tend to crumple up very easily not allowing an exact measurement of the content, and to warm it up you might have to do so in another container which means more washing anyways.

I successfully used these bottles for 2 kids. They were great. My mom also used them for my siblings back in the day.

Liked these when I HAD to use them. You don't have to worry about having to clean the bottom of a bottle when you can just toss these away...

I tried several different brands of bottles because my daughter had colic. My mom kept telling me to use these bottles. I finally listened to her and bought them. Although I can't say they helped the colic, I am glad I trid them. When my son was born, I knew I would use them again. It is costly having to buy the liners but it makes the bottles easier to clean and that is worth it to me.

I used these for both my girls when they were babies, they are very convenient. As a new mom, or dad people don't have a lot of extra time on their hands. These make life easier, and get the job done fast. A few times though out of the hundreds of times of use I did have a problem, when pouring in milk sometimes the liner would fall through the opening of the top of bottle, and milk would spill to the floor liner and all. I think it had to do with not lining up the liner with the mouth of the bottle quite right. At 2 in the a.m. my vision isn't so great. But 9 times out of 10 these were awesome.

Playtex Drop-In Liners are fast, convenient and totally mom-friendly. The shaped opening of the liner allows for easy handling and bottle preparation. They also allow for quick warming in a cup of water.

My mom used these for us when we were little, they were a breakthrough and lifesaver back then! I like these, but not as much as Dr. Brown's bottles. The good news is that these are great for on-the-go, as cleanup involves tossing the drop-in. The bad news is that these create a lot of waste, and you are always spending money on the drop-ins.

These are. Good when you are traveling, just throw after us. However, you will always have to be spending money on liners. Not good when you're already struggling.

I like them just hate that I have to push the bag up
